I would have given it five stars with with a couple of changes:  higher walls like my other cat tree ordered from Wayfair—my kitty likes feeling hidden—and sissies wrapped posts instead of just the one small part of one post.  The flat tier is a perfect leveling fit to my sofa and makes for a perfect sofa side table; doubling as a feeding platform keeping temptation away from my dog!  Gabby loves her new perch.  Far better than the ones in pet stores.
